Hello, I'm trying to send a mail with Google SMTP using OAuth2 as authentication but I get "Invalid sequence for AUTH XOAUTH2!" as exception.
I'm on trial mode to evaluate the library before purchase.
I followed this guide: https://www.emailarchite...dk/html/object_oauth.htm
The Google OAuth client is correctly configured.

What should I look for?

Thank you

Hi, thanks for using our software.

It looks that you didn't enable SSL/TLS connection, did you set
oServer.ConnectType = SmtpConnectType.ConnectSSLAuto

After you install EASendMail on your machine, please refer the sample project in

C:\Program Files (x86)\EASendMail\Samples_NetDesktop\C#\Oauth

It is well tested.
